Import PCB from Altium

Hello

Is there some mean to transfer a PCB design from Altium Designer to Allegro PCB SI. Altium has plenty export options (unfortunately without Allegro), but Allegro SI very few. At first glance it seems that there is no "intersections".

How to proceed ?

Had somebody a similar experience ?

Sure there is DXF at both sides, but does it work correctly ?

Thanks in advance.

Pavel.
